The United Rebel Alliances (URA) is a insurrectionist faction that was formed to help the URF. However, shortly after it's formation, the URF was finally destroyed on Venezia. The URA took it upon themselves to declare the Second Insurrection. However, the United Rebel Alliances eventually met it's end when it's last fortress on Earth was destroyed by the Sangheili Imperial Armed Forces during the Second Human-Sangheili War. It, however, inspired the creation of the Union of Socialist Rebellion and sent out the message that the URA tried to send, the UNSC is corrupt.
